Turning now to Sheet 2,; of'thedrawingsillustrating the invention as applied to a stick seat, the seat 1 is designed tocoinbinelighb ness and strength and is'of such form that whenfolded orcollapsed as: shownin Fig.5, it forms a convenientfhandle by which the stick maybe carried "andiwhen erect Fig. 7-

The seatl'is hinged 'along'the 1-ijii'e'j2 that upon the upper end of the stick. The upper edges of the said brackets 3 are formed into tapered bosses 6 which are drilled to receive the pins 8 which passdiagonally through and are screwed into the body of the seat thus forming hinged connections between the swinging brackets 3 and the seat 1 along the diagonal lines shown in theplan Fig. "8of the seat erected and also in the"horizontalsection 'a'longG; D, Fig. 10 ofthe seat collapsed.
